NIKSUN? Thoughts?

All: I've been digging for more information about NIKSUN, http:// www.niksun.com, and found this sort-of informative post here, <http:// www.gossamer-threads.com/lists/nanog/users/125959#125959>, which got me to join in here and ask if anyone has had more experience with them recently. I'm taking a look at their "Enterprise" kit, so far, so good, I'm able to place the probes at egress points in my network and get down to packet / other data wherever through a single interface and avoid "probe hopping", but before I expand my trial a bit more - anyone used this before? The prior poster(s) just seemed to be using only a single product like old Sniffers & I'm curious about bigger deployments. /dmfh
